You work in a furniture repair shop and are taking apart an old table to refinish it. you are trying to remove a bolt with a wrench. you tried a wrench size of  1⁄2  inch but found that it was slightly too big. your wrenches are sized in  1⁄16-inch increments.

You need to find the size of the next wrench down, so you need to subtract fractions.  first step is to state the equation you need to solve.1/2  -  1/16then we need to find a common denominator.  we can just multiply 1/2 by 8 because 16 is a multiple of 2.8( 1/2 )  -  1/168/16  -  1/16now, we subtract! 8/16  -  1/16  =  7/16hope this !
